摘要
目的 探讨LEO支架辅助栓塞治疗前交通宽颈动脉瘤的方法和策略，并评价其安全性和有效性。方法 2010年6月至2013年1月对15例前交通宽颈动脉瘤患者行LEO支架辅助栓塞治疗宽颈动脉瘤，术后随访6 ～ 24个月。分析动脉瘤形态和位置、与载瘤动脉的关系、治疗操作过程以及临床、影像随访结果。结果 15例均成功植入LEO支架，支架远端位于同侧A2段13例，位于对侧A2段2例。完全栓塞（包括致密栓塞和近完全栓塞）14例（93.3%），部分栓塞1例（6.7%）。术中支架诱发血栓形成2例（13.3%），予盐酸替罗非班动脉内灌注，支架完全通畅。DSA和（或）CTA随访6 ～ 9个月，无一例复发。结论 前交通宽颈动脉瘤LEO支架辅助栓塞技术可行，安全有效，动脉瘤完全栓塞率高，支架长期疗效有待进一步随访。
Objective To explore the therapeutic method and strategy for the wide-necked anterior communicating artery aneurysms （ACoA） by using LEO stent- assisted embolization technique, and to investigate its feasibility and efficacy. Methods During the period from June 2010 to Jan. 2013, a total of 15 patients with wide-necked ACoA received LEO stent-assisted coil embolization. All the patients were followed up for 6 - 24 months. The morphology and location of the aneurysm, the relationship between the aneurysm and its parent artery, the manipulation as well as the clinical results and radiological findings were analyzed. Results LEO stent was successfully implanted in all the 15 patients. The distal segment of the stent was positioned in the ipsilateral A2 segment in 13 cases, and in the contralateral A2 segment in 2 cases. Complete occlusion was achieved in 14 patients （93.3%）, partial occlusion in 1 patient （6.7%）. Stent- induced thrombosis occurred in 2 cases （13.3%）, after arterial perfusion with tirofiban the stent became completely open. Follow- up examinations with DSA and/or CTA were conducted in 6 - 9 months, and no recurrence was seen. Conclusion For the treatment of wide-necked anterior communicating artery aneurysms, LEO stent-assisted embolization technique is feasible, safe and effective, and the complete obstruction rate is higher. Nevertheless, the long-term efficacy needs to be further clarified.
